We're dividing 74288460 by 781 
The aim is to understand the frequency of 781 in 74288460.

Moving on to step 1:
781 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 781

On to step 2:
The number 781 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 781

Going ahead to step 3:
If we divide 742 by 781, we get 0 and a remainder of 742.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 742 to get 742.
Grab the next digit (8) from the dividend, add it to 742, then carry on: 7428 / 781

Moving on to step 4:
When dividing 7428 by 781, we get 9 with a remainder of 399.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7029 from 7428, we get 399.
Grab the next digit (8) from the dividend, add it to 399, then carry on: 3998 / 781

Advancing to step 5:
If we divide 3998 by 781, we get 5 and a remainder of 93.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
The remainder is 93 after subtracting 3905 from 3998.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 781

On to step 6:
The number 781 fits into 934 1 times, leaving a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
Deduct 781 from 934 and we're left with 153.
Bring next digit (6) of the dividend behind the 153 and repeat the process: 1536 / 781

Moving on to step 7:
The number 781 fits into 1536 1 times, leaving a remainder of 755.
Write down 1 as next digit of the result. 
Result so far: 9511.0
Subtract 781 from 1536 to get 755.
Append the next digit (0) from the dividend to 755 and continue with: 7550 / 781

Advancing to step 8:
If we divide 7550 by 781, we get 9 and a remainder of 521.
Record the quotient 9 as the next digit in the result. 
Result so far: 95119.0
If we subtract 7029 from 7550, we get 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 9:
781 goes into 5210 6 times with a remainder of 524.
Record the quotient 6 as the next digit in the result. 
Result so far: 95119.6
Subtract 4686 from 5210 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 10:
781 can be fit into 5240 6 times, resulting in a remainder of 554.
Record the quotient 6 as the next digit in the result. 
Result so far: 95119.66
If we take 4686 away from 5240, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

The final outcome is 95119.66, with a leftover of 0.554.
